YouTube updates unique reach calculation, adds music for still image posts
Summary
YouTube introduced a new Unique Reach metric for creators to better estimate audience exposure on CTV by modeling co-views (multiple viewers per TV session) and validating those estimates against partners such as Nielsen. The metric uses demographic, genre and time-of-day signals to predict viewer counts, so advertisers should treat the numbers as model-based estimates rather than absolute logged-user counts. YouTube also rolled out the ability for eligible creators to add music to still-image posts and carousels in the Shorts feed, allowing up to 10 photos with audio from the YouTube audio library or Dream Track. Brands and creators should note the shift toward TV-style measurement when evaluating CTV audience stats and consider how the new creative option can enhance Shorts engagement.
